<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Hello,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I am successfully using QVTKWidgets with one nagging exception. Despite my best efforts at handling the smart and non-smart pointers, I get an exception caused by something
in VTK when trying to exit the application.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">All smart pointers in VTK (and ITK) are handled by setting to NULL rather than deleting, and all is fine until the very end, when something during the Qt deletion ends up calling
~vtkFreeTypeToolsCleanup which causes the exception.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I do not know if this helps but I am calling theQvtkWidget->SetRenderWindow(NULL); before delting the ui (and which does not give any problems). I am not doing anything for
the interactors, as unclear whether I should even be doing this, and I do not see a corresponding call for the interactors anyway.<o:p></o:p></span></p>
